摘　　要：有机气溶胶作为大气颗粒物的主要组成部分,对气候、空气质量和人体健康造成重要影响。鉴于有机气溶胶在大气中复杂的化学结构及其动态变化,对有机气溶胶进行高时间、高化学分辨率的测量是研究有机气溶胶来源及生成机制的关键。本文综述了多种近期发展的有机气溶胶在线测量仪器的结构、工作原理及应用,介绍的仪器包括在线气溶胶质谱仪、热脱附气溶胶气相色谱仪、气溶胶化学分析入口–质子转移反应飞行时间质谱仪、基于气体和气溶胶的过滤器进样口的化学电离质谱仪和萃取电喷雾电离飞行时间质谱仪等。重点总结了近年来这些技术在大气有机气溶胶外场观测中的应用,以及在有机气溶胶组分表征和来源解析等方面的进展。探讨了目前有机气溶胶在线测量中亟待解决的难点,并对测量技术未来的发展趋势进行了展望。Organic aerosol(OA),as the main component of atmospheric particulate matter,has a great impact on climate,air quality,and human health.Due to the complex chemical structure and dynamic variation of OA in the ambient atmosphere,online measurement techniques with high time and high chemical resolutions are critical for studying of the sources and formation mechanisms of OA.In this study,the structure,working principle,and application of several recently developed instruments for OA online measurement were comprehensively reviewed.The instruments introduced here mainly include online aerosol mass spectrometers(AMS),thermal desorption aerosol gas chromatograph mass spectrometer(TAG-GC/MS),proton-transfer-reaction time-of-flight mass spectrometry coupled to a chemical analysis of aerosol online particle inlet(CHARON-PTR-MS),chemical ionization mass spectrometer coupled with a filter inlet for gases and aerosol(FIAGERO-CIMS),and extractive electrospray ionization time-offlight mass spectrometers(EESI-ToF-MS).The recent applications of these online techniques in field studies,and the progress in the composition and source analyses of OA,are summarized.Finally,the current problems that need to be solved urgently for the online measurement of OA are systematically discussed,and a trend of future development of OA online measurement techniques is proposed.
